PC Randomly Shutting Down.

[Arctic_OS]

For some reason my PC keeps shutting down when under medium load.

It doesn't BSOD, it just straight away shuts off...

I discussed possible reasons with a friend of mine and we came to the conclusion that it is most likely a poorly performing PSU, however I'd like to be more sure before I invest in a new one.

 

Here are my PC Specifications:

 

CPU: AMD FX-6300 - Stock Clock.

GPU: EVGA GTX 750 FTW

Memory: 8 GB DDR3 

HDD: WD Blue 1TB

PSU and Case: http://www.thermaltake.com.au/products-model.aspx?id=C_00001772

 

If anyone could assist me on what steps I can take to determine the cause of this issue, that would be great

what kind of temperatures are you seeing? the cpu could be overheating and shutting down

I haven't checked, given that I heard AMD CPU temperature readouts are quite inaccurate.

However if you can direct me to some CPU temperature software you believe would give you a fair idea, I can get those figures for you.

hw monitor gets the job done

Its probably the PSU. Usually cases that come with PSU's are crap.

I ran a test to see what temperatures are like.

Reaches 85 celcius and then shuts off, saw CPU usage peak at 99% and then turned off.

I thought when it reaches that high temperature or CPU usage it should either BSOD or thermal throttle so it doesn't crash?

I'm using a stock cooler by the way.

Hey Arctic_OS,

 

I would look online for some guide on how to test the PSU if it's working properly. I would also get another one to test the system with it just to determine if the problem is caused by it or by something else. Are you using a custom CPU Cooler on the CPU? 

85 degrees is too high for safe performance for the CPU so I would suggest to either optimized the cooling of the CPU (internal airflow and the CPU Cooler itself, or check if it's not faulty (the thermal paste might be damaged, the CPU itself may be faulty).

As Captain_WD suggests: see if you can improve thermals. Changing thermal paste should work fine.

To test the PSU, use a multimeter to measure voltage levels on the 24-pin connector. Check that 12V, 5V, and 3.3V lines fall within spec under load.
